Behave badly (3,2)

Ross

I believe the answer is:

act up

'behave badly' is the definition.
(act up can mean to misbehave)

This is the entire clue.

(Other definitions for act up that I've seen before include "Behave like a brat" , "take part in heightened drama?" , "Give trouble, make a fuss" , "create fireworks display?" , "Become unpleasant" .)

I've seen this clue in The Washington Post, the L.A. Times Daily, the Universal, The Sun, The Guardian, the USA Today and The Telegraph.
